USP9Y and Infertility: Interestingly, six (6) coding (AMELY, PCDH11, SRY, TGIF2LY, TSPY3, and USP9Y) and ten (10) non-coding (TTTY2, TTTY4C, TTTY5, TTTYY6, TTTY8, TTTY10, TTTY14, TTTY21, TTTY22, and TTTY23) genes exhibited a common bimodal pattern of expression characterised by low expression in samples from fertile patients while high expressions were associated with infertility (Fig. 2).
